ECG Ruler and Interpretation Card, ID Card Size

A pocket-sized ECG ruler and interpretation card built by paramedics for use in the field, classroom or ward. Slides into an ID badge holder, clips to a lanyard, and gives you a structured approach to rhythm and ST analysis without pulling out a textbook.

Features:

• 8-step interpretation method: a structured approach to ECG assessment
• ST-elevation ruler with STEMI criteria: thresholds by sex and age group
• Axis interpretive key: work out axis at a glance
• Interval measurement: heart rate, PR, QRS, QT intervals and ST elevation or depression
• Durable build: 0.76mm thick transparent plastic that will not bend or crease
• ID card size: 85.5 x 54mm, fits standard ID and badge holders
• Lanyard hole: punched for quick attachment

Suited to paramedics, student paramedics, nurses, medical students and other healthcare professionals who read 12-leads regularly. Lay the transparent ruler over a printed ECG to measure intervals directly, then work through the 8-step method on the reverse to confirm rhythm, axis and ischaemic changes.

How to read an ECG with a ruler: align the ruler with the printed ECG, count small squares to measure PR, QRS and QT intervals, then use the ST-elevation scale to check STEMI criteria against the patient's age and sex.

Australia uses ECG as the standard term, though ECG and EKG refer to the same 12-lead recording.
